(54) A method to control pressures in vertical escape routes


(57) The present Invention relates to a method of controlling pressures in vertical escape routes for the purpose of securing vertical escape routes, characterised in that the amounts of supplied and discharged air depend on the temperature value in the vertical escape route 1 and the external temperature, which are transmitted from the temperature sensor 4 located in the vertical escape route 1 and from external temperature sensor 5 into the central control unit 6, which activates, based on the computed difference of temperatures, the reversible upper fan 7 and the reversible lower fan 8, as well as the upper pressure-regulating governor 9 and the pressure-regulating governor 10.
